Style a tooltip or popup — tooltip

Builds a styling specification for map tooltips and popups, mirroring legend_style(). Pass the result – or simply a preset name like "dark" – to the tooltip_style / popup_style argument of a layer function or add_flowmap(). Start from an optional light/dark preset and override any individual properties on top of it. With no styling argument supplied, tooltips keep their default (unstyled) appearance.

Usage

tooltip_style(
  preset = NULL,
  background_color = NULL,
  background_opacity = NULL,
  text_color = NULL,
  border_color = NULL,
  border_width = NULL,
  border_radius = NULL,
  font_family = NULL,
  font_size = NULL,
  font_weight = NULL,
  padding = NULL,
  max_width = NULL,
  shadow = NULL,
  shadow_color = NULL,
  shadow_size = NULL,
  position = NULL,
  offset = NULL
)

popup_style(
  preset = NULL,
  background_color = NULL,
  background_opacity = NULL,
  text_color = NULL,
  border_color = NULL,
  border_width = NULL,
  border_radius = NULL,
  font_family = NULL,
  font_size = NULL,
  font_weight = NULL,
  padding = NULL,
  max_width = NULL,
  shadow = NULL,
  shadow_color = NULL,
  shadow_size = NULL,
  position = NULL,
  offset = NULL
)

Arguments

preset: Optional base theme: "light", "dark", or "auto" (resolve to light or dark from the flowmap dark mode; ordinary layers treat "auto" as light). Individual arguments below override the preset.
background_color: CSS color for the tooltip/popup background.
background_opacity: Numeric in [0, 1] for the background opacity.
text_color: CSS color for the text.
border_color: CSS color for the border.
border_width: Border width in pixels.
border_radius: Corner radius in pixels.
font_family: CSS font-family string.
font_size: Font size in pixels.
font_weight: CSS font-weight.
padding: Internal padding in pixels.
max_width: Maximum width as a CSS size (e.g. "320px").
shadow: Logical; whether to draw a drop shadow.
shadow_color: CSS color of the drop shadow.
shadow_size: Blur radius of the drop shadow in pixels.
position: For flowmap tooltips/popups, "floating" (cursor-following) or "anchored" (pinned to the feature). Ignored by ordinary layers.
offset: For floating flowmap tooltips, a numeric pixel offset or a length-2 numeric c(x, y).

Value

A list of class mapgl_tooltip_style.
